This code is called a [[UNO_registery_and_Bootstrapping#The_Bootstrap|bootstrap]] and uses <idl>com.sun.star.lang.XMultiServiceFactory</idl>, <idl>com.sun.star.uno.XInterface</idl> and <idl>com.sun.star.frame.XComponentLoader</idl> interfaces and <idl>com.sun.star.frame.Desktop</idl> service.

Remember each time you query for an interface you have to add code lines (if they don't exist) in the source code and a line in the makefile. I will generally add comments to prevent omissions. You can find more explanations [[IDL_Files_and_Cpp#IDL__and_C.2B.2B|here]] (if you are not a beginner).

{{Documentation/Note|'''Important Note''' : The more important point in the compilation chain of the examples above is that <code>cppumaker</code> will construct every hpp and hdl files you need in your application. The SDK doesn't  provinde every hpp files, but you have to construt them starting from IDL files provided by SDK.}}
+
{{Documentation/Note|It is possible to construct all the hpp files when installing the SDK as [[SDKInstallation#Other_Windows_Installations_descriptions|mentioned in a Windows]] installation. It's also possible with other OS. In doing so, you don't need modifying your MakeFile.}}

Note : You have eventually to change "port=8100" into "port=2083" for recent SDK (after 2.X).

You can have a look at :

  1. com.sun.star.uno.XComponentContext, com.sun.star.lang.XMultiComponentFactory, com.sun.star.uno.XInterface, com.sun.star.bridge.XUnoUrlResolver and com.sun.star.lang.XMultiServiceFactory interfaces,
  2. com.sun.star.bridge.UnoUrlResolver service
